Sorry for missing the file.
@ivan4th needs to take a look at that. My first suspicion would be a problem with the Node Id AVP, but it could be something else.

Yes, I will take a look at that, looks like IPv4 Node ID lookup is not done correctly due to ip46_address_t with uninitialized bytes being used as a hash key. Thanks for the report

@orion-belt sorry, it was a bit of red herring. After trying to reproduce the problem I understood there's really no bug in the Node ID handling code and IP-based Node IDs are handled just fine. The actual problem here is clock skew. Please note that at 14:19:02 your control plane sends PFCP Association Setup Request with Recovery Timestamp at 14:11:17 UTC, so basically the association is already expired even before it's started; that's also why there are no PFCP Heartbeat Requests from the UPG side in the next 50s before a Heartbeat Request from the control plane. So, please adjust the clock and try again :)

can you provide an pcap of the PFCP exchange, starting with the the Association Request, please?

Hi @RoadRunnr,
It is already there in above message.
(I am using image-debug of upg-vpp)
In pcap it can be seen that pfcp node has associated with upg.

@ivan4th has this been fixed in the meantime?

@ivan4th your explanation make no sense to me. Having a Recovery Timestamps in the past is perfectly ok. There would only be a problem when it is in the future.

@RoadRunnr yes, you're correct. Trying to understand why no heartbeat requests are sent from the UPG though...

@ivan4th @RoadRunnr
One different thing I noticed here here is IE Enterprise specific type is different in association response and session establishment response.
Is could be the reason for session failure ?

I have rebuilt source with latest code and I no longer see this issue.
